[Leica] re Doug Sharp's lens hood

[Thinkofcole at aol.com (Thinkofcole@aol.com)]

    If you believe you can improve on the knife blades inside the lens hood, 
you might try. But I have destroyed expensive stuff by attempting to improve 
on it. 
    On the lens -- if I understand you correctly, I definitely would not 
attempt to put anything like resin in the ridge or anywhere on the lens that you 
can't remove, with say, nail-polish remover [acetone]. 
   Someone suggested that you try plastic electricians tape inside the hood. 
I think that might be quicker than putting felt inside. The most you can lose 
if you tamper with the hood is the hood, worth about $50. That's as far as I 
personally would go.-- regards, bob cole
